The PhD thesis work by Rahul Prasanna Kumar has resulted in the development of a method for 3D visualization of blood vessels that is nearly 20 times faster that many commonly used methods. Such fast methods are useful for many medical applications that involve diagnosis, therapy, and also in planning and navigation of surgeries.
Accurate and fast 3D visualization of blood vessels are important for liver surgery or resection. Liver resection can be performed by “formal resection”, or “parenchyma-sparing technique”. In the parenchyma-sparing technique, the surgery is performed such that only the region that has the cancer is removed, compared to formal resection that is the commonly used technique where the anatomical half of the liver that contains the tumor is removed. Thus, the parenchyma-sparing technique helps in saving a significant part of the patient’s liver, which increases the possibility of having multiple resections when cancer reemerges. However, this technique requires a thorough planning of the individual surgical strategy, i.e. an accurate visualization of the liver and its structures, especially the blood vessels. The method proposed in the thesis can help the surgeons in visualizing blood vessels for planning a liver surgery.

Nikolai Hiorth was awaded the prestigeous Young Investigator Award at the 26th International Conference of the Society for Medical Innovation and Technology (SMIT) in Shanghai, China, from 18-20 September 2014. Nicolai Hiorth's presented "Endovascular Repair of the Mitral Valve" about a new minimally invasive catheter based concept for mitral valve repair developed in collaboration with senior cardiac surgeon dr. Jacob Bergsland and others from The Intervention Centre. During the conference dr. Bergsland also presented the project "In-vivo Demonstration of High Data Rate Implant Communications Using Ultra Wideband", and PhD research fellow Rahul Prasanna Kumar the project "Fast and User-friendly Blood Vessel Segmentation Using 2D Cross-sectional Analysis".
Airazat M. Kazaryan was awarded His Majesty Norwegian King’s Gold Medal in Medicine for 2014 based on research on outcomes from surgeries performed by a group of surgeons led by professor Bjørn Edwin from The Intervention Centre. The medal was received under the Annual Festival at the University of Oslo's aula September 2nd, 2014. The ceremony was followed by a reception at Domus Bilbiotheca. In the evening the Prize winners were invited to Gala dinner hosted by University of Oslo.
On 28.05.2014 Fredrik Halvorsen, MD defended his thesis on Virtual Reality Simulation in Laparoscopic Surgical Education at Faculty of Medicine, University of Oslo. The commission judging the work was; professor Jørn Kjæve, Institute for Clinical Medicine, University of Tromsø, associate professor Ronald Mårvik, Institute for Cancer Research and Molecular Medicine, Norwegian University of Science and Technology, Trondheim and professor Egil Johnson, Institute for Clinical Medicine, Univerity of Oslo. On the image dr Halvorsen is flanked by his mentors professor Erik Fosse (left) and dr Odd Mjåland.
The Physicists at The Intervention Centre hosted the Regional CT-Forum on May 6th 2014. Last Regional CT Forum focused on CT of the Liver. This time the focus was CT of the thorax. 120 radiologists, radiographers and physicists representing all hospitals in the South-Eastern Norway Regional Health Authority attended the Forum. Among topis discussed were; surgical consequences of the investigation, treatment of emphysema with bronchial valves, image quality and radiation dosis in CT thorax, contrast optimalization, protocols and pitfalls in lung emboli, protocols and pitfalls in tumor protocols, spectral imaging and finally ultra low dose CT thorax. The meeting was rounded up with plenary discussions.
Before easter 6 research groups were rewarded 50.000 NOK each by Oslo University Hospital for exceptional publications with high impact published during during 2. half of 2013. Among the price winners were dr. Kyrre Eeg-Embem from The Intervention Centre. Eeg-Emblem et.al's paper entiteled Vessel architectural imaging identifies cancer patient responders to anti-angiogenic therapy was published in Nature Medicine. Dr. Eeg-Emblem is number three from left on the picture. Announcement on the hospital web portal (Norwegian text)
The Intervention Centre, in cooperation with Hermes Partnership and COST Action IC0905-TERRA, organized the “Workshop on Sensor Communications & Technologies, Body Area Networks, e-Health Services and Standardization.” This event took place on April 4, 2014, in Florence, Italy, in the framework of the 8th International Symposium on Medical Information and Communication Technology (ISMICT) sponsored by the Institute of Electrical and Electronics Engineers (IEEE). The workshop consisted of high quality technical presentations and a general discussion in which the participants identified future trends and new research directions for the advancement of medical sensing technology. Dr. Raúl Chávez-Santiago from the Intervention Centre delivered the keynote talk “Dual-Band Cognitive Radio for Wearable Sensors in Hospitals,” in which he emphasized the need for novel and more effective techniques to mitigate interference in sensor networks for healthcare.
Aasmund Fretland was awarded the 500 USD prestigeous "Best Oral Poster Presentation Price" at the 11th World Congress of the International Hepato-Pancreato-Billary Association in Seoul, Korea, March 22-27 2014. The presentation concerned IL-6 in patients included in the ongoing randomised clinical trial Oslo-CoMet Study. The principal investigator of the Oslo-CoMet Study is professor Bjorn Edwin from The Intervention Centre. The picture shows Aasmund Fretland presenting the poster at the conference that gathered around 2500 international delegates.
Research Council of Norway hosted an Idea Lab with the topic : "Towards a zero emission society". During 5 hectic days 27 selected researchers from different disciplines generated four project proposals. The project group behind "Holistic monitoring of indoor environment" included professor Ilangko Balasingham from The Intervention Centre. The research challenge in this projectis how energy consumption can be radically reduced by use of rapidly responding technologies and materials. (Photo:Forskningsrådet)
On January 13-14, 2014, the Nordic Chapter of the International Society for Magnetic Resonance in Medicine (http://www.ismrm.org/nordic/) with Kyrre E. Emblem (chair) and Atle Bjørnerud from the Intervention Centre organized a two-day ‘hands-on’ course in neuro MRI: Perfusion, Diffusion / DTI and BOLD-fMRI analysis at Rikshospitalet, Oslo University Hospital.
Invited speakers where experts from the Nordic countries and they shared their knowledge on advanced neuro MRI with over 80 participants in total.
On October 24 2013 Andreas Espinoza defended his thesis on Myocardial monitoring by epicardial ultrasonic transducers. Andreas Espinoza and co-workers have developed an ultrasonic system for attachment on the heart for continuous assessment of myocardial function during cardiac surgery. As the patients undergoing cardiac surgery are getting older, and the surgical treatment is increasingly complex, this risk for complications increase. Perioperative ischemia is an important predictor for adverse patient outcome. Echocardiographic assessment for early detection of myocardial ischemia is superior to ECG or hemodynamic monitoring, but is performed intermittently.
